Resolution to Award a Construction Contract to E.T. MacKenzie Co.
($3,610,140.81; Bid No. 3908) for the Miller - Maple Transmission Water Main Project
Memorandum
Attached for your review and approval is a resolution to award a construction contract to E.T. MacKenzie Co. in the amount of $3,610,140.81 for the Miller - Maple Transmission Water Main Project.
The Miller - Maple Transmission Water Main project includes the construction of approximately 9,834 LF of 24” Water Main and appurtenances, 2,800 LF Storm Sewer, 2,030 LF of sludge discharge force main and all related work. In addition, this work includes approximately 2,400 LF of curb and gutter and full and partial width road restoration.
An earlier study of the water supply system by Black & Veatch determined that a 20-inch transmission water main extending from the treatment plant to the intersection of Maple Road and Dexter Road would be necessary to supply Scio Township with the City water. Furthermore we determined that this would be an opportunity to enlarge the proposed 20-inch water main for the Scio Township to a 24-inch main to provide additional capacity that the City may need for the West High Service Area customers. Further considerations were given to add to the water main project, the installation of a new storm sewer line and the upgrades to the “spent lime stone” handling system, for more efficiencies and cost savings.
The total project cost is estimated at $5,231,144.00, as shown below:
Design Engineering $ 361,014.00
Construction Contract, Including Contingencies $ 3,971,155.00
